Rigid Body (sings).

Gin a body meet a body
Flyin- through the air,
Gin a body hit a body,
Will it fly? and where?
Ilka impact has its measure,
Ne-er a ane hae I,
Yet a- the lads they measure me,
Or, at least, they try.

Gin a body meet a body
Altogether free,
How they travel afterwards
We do not always see.
Ilka problem has its method
By analytics high;
For me, I ken na ane o- them,
But what the waur am I?
